11. Repeat this procedure for all cutting units to be
backlapped.
12. When backlap operation has been completed,
return the backlap switch to OFF, lower the seat
and tighten both locking bolts securely, and
wash all lapping compound off the cutting units.
Adjust cutting unit reel-to-bedknife as needed.
IMPORTANT: If the backlap switch is not
returned to OFF position after backlapping, the
cutting units will not raise or function properly.
IMPORTANT: If the cutting units are removed
for backlapping (such as when bedknives are
changed) the reel speed sensors must be removed
from the left front and the left rear cutting units.
Before backlapping, install and torque a 9.5 mm
(3/8") capscrew in the left end of the reel shaft
with which to drive the reel when backlapping.
DO NOT attempt to use the capscrew which
attaches the magnet to drive the reel for backlap-
ping, this capscrew must be torqued to a maxi-
mum of 5 ft-lbs. to avoid damage to the magnet.
